Travis Kelce scored a stunning walk-off touchdown and Patrick Mahomes made history as the streaking Kansas City Chiefs topped the Los Angeles Chargers 34-28 in overtime on Thursday.

Kelce and star quarterback Mahomes combined for a 34-yard touchdown to lift the AFC West-leading Chiefs (10-4) past the Chargers (9-6) in the additional period for their seventh straight victory.

Mahomes – who finished 31-of-47 passing for 410 yards, three touchdowns and an interception – took his tally to 152 touchdowns in 60 NFL games, the former MVP becoming the fastest player to reach 150 combined rushing and passing TDs after eclipsing Hall of Famer Dan Marino (61 games).

The Chiefs rallied in Los Angeles, where the Chargers were fuelled by Justin Herbert – who threw a touchdown pass and ran for another score to put the hosts 14-10 ahead at half-time.

After Kansas City's Harrison Butker's field-goal made it a one-point game in the third quarter, the two teams traded touchdowns in a wild fourth period.

The Chargers led 21-13 and 28-21, but the Chiefs responded on both occasions – Mahomes throwing touchdowns passes to Tyreek Hill and Kelce as Kansas City forced overtime.

That Mahomes-Kelce combination proved decisive with less than nine minutes left on the clock in OT after the latter weaved his way through the Chargers' defence to spark wild celebrations.

Hill and Kelce became the first wide receiver/tight end duo in NFL history to each have at least 10 receptions for 140 yards and a touchdown in the same game, per Stats Perform.
